barcode-scanner-mcp
MCP server for scanning and generating barcodes and QR codes.
Use Cases
Decode a barcode from a photo: "What does this barcode say?" → reads the image, detects the barcode format, and returns the decoded text.
Generate a QR code: "Create a QR code for https://example.com" → generates a PNG QR code image with configurable error correction.
Create shipping labels: "Generate a Code 128 barcode for tracking number 1Z999AA10123456784" → produces a barcode image in the specified format.
Verify printed barcodes: "Scan this product barcode and look up the item" → decodes the barcode and returns the text for further lookup.
Setup
Follow the instructions on install-mcp, which generates the right config for your MCP client (Claude Code, Claude Desktop, Cursor, Cline, VS Code, and more).
